Description

Technical Field

[0001] This application relates to the field of home appliance technology, and more particularly to a refrigerator. Background Technology

[0002] With the improvement of living standards, refrigerators have become an indispensable household appliance in people's daily lives. As a direction for refrigerator development, intelligentization is now a key focus of research and development for many refrigerator manufacturers.

[0003] In the process of conceiving and implementing this application, the applicant discovered at least the following problems: Currently, most products install the microphone at the bottom cover and the voice module at the top of the door, resulting in a longer connection between the microphone and the voice module, which leads to more severe signal attenuation. Therefore, in order to reduce signal attenuation, it is generally necessary to add a shielding cable, which results in a higher cost for the entire smart system.

[0004] The preceding description is intended to provide general background information and does not necessarily constitute prior art. Utility Model Content

[0005] The main objective of this application is to provide a refrigerator that improves the accuracy of voice recognition, reduces the risk of signal attenuation, and reduces the complexity of electrical connections.

[0006] To achieve the above objectives, in a first aspect, this application provides a refrigerator, comprising:

[0007] The enclosure includes a refrigeration compartment;

[0008] A door, movably connected to the enclosure and configured to open and close the refrigeration compartment, includes:

[0009] The top cover is located at the top of the door.

[0010] Display components include:

[0011] The display box is installed on the upper part of the door and has a first receiving cavity;

[0012] The display panel is installed inside the first receiving cavity;

[0013] Voice interaction components, including:

[0014] A microphone is installed inside the first receiving cavity;

[0015] The sound-generating component is electrically connected to the receiver and is mounted on the bottom surface of the upper cover;

[0016] The main control board is located on the display board and is electrically connected to the display board, the radio and the sound-emitting components.

[0017] The display panel and the main control board are stacked along a first direction, which is the direction from the front of the cabinet to the rear of the cabinet.

[0018] The beneficial effects of this application are as follows: By setting up the voice interaction component and the display component, the display component is placed on the door and at the same height as the person. Since the microphone is placed inside the display box, it is also at the same height as the person, which is conducive to the microphone receiving voice commands better and reducing the loss of voice signal during transmission, thereby improving the accuracy of voice recognition. In addition, the closer distance between the microphone and the display board shortens the length of the connecting cable, which not only reduces material costs but also reduces the risk of signal attenuation and may eliminate the need for additional shielding of the signal cable. Furthermore, the integration of the main control board and the display board allows them to share a power supply, reducing connection complexity and further reducing production and maintenance costs, while making more efficient use of the internal space of the display box.

[0019] Based on the above technical solution, the following improvements can be made to this application.

[0020] In some embodiments, the display panel has a mounting area, and the main control board is assembled in the mounting area.

[0021] The above technical solution has the following advantages or beneficial effects: By directly mounting the main control board in the installation area of ​​the display board, the internal space occupied by the device is reduced, making the device design more compact and integrated. The integrated design reduces the number of components that need to be manufactured and assembled separately, thereby reducing manufacturing and assembly costs. The direct connection between the main control board and the display board shortens the signal transmission path, reducing signal delay and attenuation.

[0022] In some embodiments, an inner door liner is provided on the inner side wall of the door body;

[0023] The refrigerator also includes:

[0024] The protective component is located on the outer wall of the display box and between the display box and the inner liner of the door. Along the first direction, the projection of the protective component is located on the mounting area.

[0025] The above technical solution has the following advantages or beneficial effects: After the main control board and the display board are integrated, the thickness of the display box in the installation area is increased, and the distance between the display box and the inner liner of the door is reduced, which makes it easy to have the risk of condensation. The protective component can play a role in preventing condensation.

[0026] In some embodiments, the refrigerator further includes an isolator disposed on the display box and surrounding at least a portion of the periphery of the radio.

[0027] The above technical solution has the following advantages or beneficial effects: the isolator can effectively isolate the radio receiver from electrostatic interference from the external environment, reduce the risk of electrostatic accumulation, and prevent electrostatic breakdown from damaging the radio receiver and related electronic components. By preventing electrostatic breakdown, the isolator protects the normal function of the radio receiver, reduces equipment downtime or performance degradation caused by electrostatic faults, and improves the overall reliability of the refrigerator.

[0028] In some embodiments, an installation opening is provided on the door body;

[0029] The display box includes:

[0030] The display box is installed inside the door through a mounting port, and the display box has an opening.

[0031] The display cover is located at the opening and on the outside of the door, and the display cover and the display box form a first receiving cavity.

[0032] The above technical solution has the following advantages or beneficial effects: By opening an installation port on the door, the display box can be easily installed and removed, simplifying the production and maintenance process. The display cover is located on the outside of the door, forming a first receiving cavity together with the display box. The display box is embedded into the inside of the door through the installation port, making reasonable use of the internal space of the refrigerator door, without affecting the internal storage space of the refrigerator, providing a clean and modern appearance design, and enhancing the aesthetics of the product.

[0033] In some embodiments, the display housing is provided with a snap-fit ​​component, and the display cover is provided with a snap-fit ​​groove. The snap-fit ​​component extends into the snap-fit ​​groove so that the display housing and the display cover snap together.

[0034] The above technical solution has the following advantages or beneficial effects: the snap-fit ​​design allows the display housing and display cover to be quickly and securely connected together without the need for additional tools or complex installation steps, simplifying the assembly process and improving production efficiency. Furthermore, the snap-fit ​​connection reduces the need for screws or other fasteners, lowering material costs and assembly time, thereby reducing overall production costs.

[0035] In some embodiments, the refrigerator further includes:

[0036] An abutment is provided on the display housing and extends toward the microphone so that the microphone abuts between the abutment and the display cover.

[0037] The above technical solution has the following advantages or beneficial effects: the addition of the abutment component, which presses against the microphone, allows the microphone to fit tightly against the inner wall of the display cover, reducing sound loss as sound travels from the outside to the inside. Simultaneously, it further improves the installation stability of the microphone.

[0038] In some embodiments, any one of the following is included:

[0039] The abutting member is an abutting plate, which has an abutting part that abuts against the side of the microphone to fix the microphone to the inner wall of the display cover.

[0040] At least one sound-receiving hole is provided on the display cover, and the sound-receiving hole passes through the outer wall and the inner wall of the display cover;

[0041] The display cover has a display surface, which is located on the side opposite to the display housing.

[0042] The display box has wiring holes located at the top of the display box, near the side of the top cover.

[0043] It should be noted that the abutment extends towards the microphone and presses it against the inner wall of the display cover. This design ensures the microphone is stably fixed within the first receiving cavity, preventing displacement or loosening during use.

[0044] In some embodiments, any one of the following is included:

[0045] The door is made of steel plate.

[0046] The sound receiving device is a microphone;

[0047] The sound-producing component is a loudspeaker;

[0048] The display components and voice interaction components are located in the same door;

[0049] The radio is equipped with an indicator light;

[0050] The upper cover has a second receiving cavity, the opening of which faces the lower side of the door body, and the sound-emitting component is installed inside the second receiving cavity.

[0051] The above technical solution has the following advantages or beneficial effects: The microphone, as a sound-receiving component, can efficiently capture the user's voice commands, ensuring the clarity and accuracy of the voice signal, thereby improving the performance of the voice recognition system. The speaker, as a sound-emitting component, can provide high-quality audio output, ensuring that the system's feedback sound is clear and loud, enhancing the user's auditory experience.

[0052] Secondly, this application also provides a refrigerator, comprising:

[0053] The enclosure includes a refrigeration compartment;

[0054] A door, movably connected to the enclosure and configured to open and close the refrigeration compartment, includes:

[0055] Display panel, installed on the door;

[0056] Voice interaction components, including:

[0057] A microphone, located on the display panel, is used to receive voice information;

[0058] The sound-generating component is electrically connected to the sound-receiving component and is installed at the top of the door.

[0059] The main control board is located on the side of the display panel and faces the refrigeration room;

[0060] After the receiver receives voice information, the main control board controls the speaker to provide sound feedback, and the main control board controls the display board to provide display feedback.

[0061] The refrigerator provided in this application includes a cabinet having a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment, the door including: an upper cover located at the top of the door; a display assembly including: a display box installed on the upper part of the door, the display box having a first receiving cavity; a display panel installed in the first receiving cavity; a voice interaction assembly including: a microphone installed in the first receiving cavity; a sound emitter electrically connected to the microphone and installed on the bottom surface of the upper cover; a main control board disposed on the display panel, and the main control board electrically connected to the display panel, the microphone, and the sound emitter respectively; wherein, the display panel and the main control board are stacked along a first direction, the first direction being the direction from the front side of the cabinet to the rear side of the cabinet.

[0062] By integrating voice interaction and display components, with the display component positioned on the door at eye level and the microphone also at eye level (since the microphone is located inside the display box), the microphone can better receive voice commands, resulting in less signal loss during transmission and improved voice recognition accuracy. Furthermore, the closer proximity between the microphone and display panel shortens the connection cable length, reducing material costs and the risk of signal attenuation, potentially eliminating the need for additional shielding of the signal cable. Additionally, the integration of the main control board and display panel allows them to share a single power supply, reducing connection complexity and further lowering production and maintenance costs, while also making more efficient use of the display box's internal space.

[0085] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. All other obtained embodiments are within the scope of protection of this application. In the absence of conflict, the following embodiments and features can be combined with each other.

[0086] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0087] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0088] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0089] Currently, in the process of conceiving and implementing this application, the applicant has discovered at least the following problems: Most current products install the microphone at the bottom cover and the voice module at the top of the door, resulting in a longer connection between the microphone and the voice module, which leads to more severe signal attenuation. Therefore, in order to reduce signal attenuation, it is generally necessary to add a shielding cable, which results in a higher cost for the entire smart system.

[0090] To overcome the shortcomings of existing technologies, the refrigerator provided in this application, through the arrangement of a voice interaction component and a display component, with the display component located on the door at the same height as a person, and the microphone located inside the display box at the same height as a person, facilitates better reception of voice commands and reduces signal loss during transmission, thereby improving the accuracy of voice recognition. Furthermore, the closer distance between the microphone and the display board shortens the length of the connecting cable, reducing material costs and the risk of signal attenuation, potentially eliminating the need for additional shielding of the signal cable. In addition, the integration of the main control board and the display board allows them to share a single power supply, reducing connection complexity and further lowering production and maintenance costs, while also making more efficient use of the internal space of the display box.

[0091] In addition, most products are designed for refrigerators with glass panel doors, and there are currently no products with intelligent voice interaction on steel doors. Therefore, the door provided in this application has display components and voice interaction components on a steel door.

[0092] The contents of this application will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the contents of this application.

[0094] like Figures 1 to 9 As shown, this application embodiment provides a refrigerator 100, including:

[0095] The enclosure 110 has a refrigeration compartment;

[0096] A door 120, movably connected to the housing 110 and configured to open and close the refrigeration compartment, includes:

[0097] The upper cover 121 is located at the top of the door body 120;

[0098] Display component 130 includes:

[0099] Display box 131 is installed on the upper part of door 120, and display box 131 has a first receiving cavity 1311;

[0100] Display panel 132 is installed in the first receiving cavity 1311;

[0101] Voice interaction component 140, including:

[0102] The microphone 141 is installed inside the first receiving cavity 1311;

[0103] The sound-emitting element 142 is electrically connected to the sound-receiving element 141 and is mounted on the bottom surface of the upper end cover 121;

[0104] The main control board 143 is disposed on the display board 132, and the main control board 143 is electrically connected to the display board 132, the radio 141 and the sound-emitting element 142 respectively.

[0105] The display panel 132 and the main control board 143 are stacked along a first direction, which is the direction from the front of the cabinet 110 to the rear of the cabinet 110.

[0106] With the above-described configuration, namely the refrigerator 100 of this embodiment, the display component 130 is located on the door 120 at the same height as a person. Since the microphone 141 is located inside the display box 131, it is also at the same height as a person, which helps the microphone 141 to better receive voice commands and reduces the loss of voice signals during transmission, thereby improving the accuracy of voice recognition. In addition, the closer distance between the microphone 141 and the display board 132 shortens the length of the connecting cable, which not only reduces material costs but also reduces the risk of signal attenuation and may eliminate the need for additional shielding of the signal cable. Furthermore, the integration of the main control board 143 and the display board 132 allows them to share a power supply, reducing connection complexity and further reducing production and maintenance costs. The internal space of the display box 131 is also utilized more efficiently.

[0107] It should be noted that the following provides a detailed explanation of each structure.

[0108] [Box 110]

[0109] refer to Figure 1 The refrigerator 100 in this embodiment may include a cabinet 110 and a door 120. The cabinet 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. There may be one or more refrigeration compartments. When there are multiple refrigeration compartments, they may be divided into a refrigerator compartment, a freezer compartment, or a variable temperature compartment, etc.

[0110] For example, the refrigerator body 110 may include an outer shell and an inner liner, the outer shell defining the external boundary of the refrigerator 100. The inner liner may be disposed within and connected to the outer shell. The inner liner may be recessed inward to form a cooling compartment. An insulation layer may be filled between the outer shell and the inner liner, which can insulate the cooling compartment, thereby reducing the energy consumption of the refrigerator 100.

[0111] The box 110 adopts a hollow cuboid structure. It is understood that in other embodiments, the box 110 may also adopt a hollow shell structure of other shapes.

[0112] [Gate 120]

[0113] It should be noted that the door 120 can be connected to the cabinet 110 to open or close the refrigeration compartment.

[0114] In some embodiments, the door 120 is a steel plate door.

[0115] It should be noted that the door 120 of this application can be a steel plate door, compared to the glass door of the refrigerator 100 in the prior art. In other words, the display component 130 and the voice interaction component 140 of this application are applied to a steel plate door.

[0116] A door 120 is disposed on the front surface of the enclosure 110 to enclose the refrigeration compartment. The door 120 is configured to open and close the refrigeration compartment, meaning it can open and close the front opening of the enclosure 110. Doors 120 can be correspondingly assigned to refrigeration compartments; that is, each refrigeration compartment can have one or more doors 120. The number of refrigeration compartments and doors 120, as well as the function of the refrigeration compartments, can be selected based on specific circumstances. One door 120 can be assigned to the same refrigeration compartment. Alternatively, two doors 120 can be assigned to the same refrigeration compartment.

[0117] like Figure 1 As shown, in some possible implementations of this application embodiment, the door 120 can be rotatably connected to the cabinet 110 about the height direction Y of the cabinet 110. The door 120 can be pulled or pushed, causing the door 120 to rotate relative to the cabinet 110 to open or close the refrigeration compartment.

[0118] In some embodiments, the door 120 is a rotating door structure. The door 120 is rotatably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a general door structure, such as a refrigerator door, a freezer door, etc.

[0119] Specifically, the door 120 and the cabinet 110 can be connected by a hinge so that the door 120 of the refrigerator 100 can rotate around the axis of the hinge, thereby opening and closing the door 120 of the refrigerator 100 and opening and closing the corresponding refrigeration compartment.

[0120] In some embodiments, the door 120 can also be a sliding door structure. The door 120 is slidably disposed on the front side of the cabinet 110, and in this case, the door 120 can be used as a drawer door. Specifically, guide rails (not shown in the figure) are respectively provided on the left and right inner side walls of the cabinet liner, and the door 120 is connected to the guide rails on both sides, thereby realizing the sliding function of the door 120 and realizing the opening and closing of the refrigeration compartment by extending and retracting the guide rails.

[0121] In some embodiments, a refrigeration assembly (not shown) is provided inside the cabinet 110 to provide cooling for the interior of the refrigerator 100 in order to maintain a low-temperature environment in each refrigeration compartment.

[0122] Refrigeration components include compressors, condensers, evaporators, and throttling devices. The specific structure and connections of these components can be found in relevant technical documentation on refrigeration components, and will not be elaborated upon here. The evaporator provides different amounts of cooling capacity to different types of storage spaces, resulting in varying temperatures within these spaces. For example, the temperature inside a refrigerator is generally between 2°C and 10°C, preferably between 4°C and 7°C. The temperature range inside a freezer is generally between -22°C and -14°C. Different types of items have different optimal storage temperatures, and consequently, different suitable storage spaces. For example, fruits and vegetables are suitable for storage in refrigerators or crisper compartments, while meat is suitable for storage in freezers.

[0123] It should be noted that the door body 120 also includes a frame. The frame is a rectangular frame structure with a hollow interior. The interior space of the frame forms the door cavity (not shown in the figure). The door cavity is mainly used to fill with foam material to achieve the heat insulation and thermal insulation functions of the door body 120.

[0124] In some embodiments, the door 120 further includes a lower end cover, an upper end cover 121, a left flange, and a right flange.

[0125] The upper end cover 121 is located at the top of the frame and serves as the top exterior surface of the door 120. The lower end cover is located at the bottom of the frame and serves as the bottom exterior surface of the door 120. The upper end cover 121 and the lower end cover are arranged in a parallel and spaced-apart configuration.

[0126] The left flange is located at the left edge of the door body 120 and serves as the left side appearance of the door body 120. The right flange is located at the right edge of the door body 120 and serves as the right side appearance of the door body 120. Both the left and right flanges are located between the upper end cover 121 and the lower end cover, and the left and right flanges are arranged in a parallel and spaced manner.

[0127] The tops of the left and right flanges are connected to the left and right ends of the upper cover 121, respectively, and the bottoms of the left and right flanges are connected to the left and right ends of the lower cover, respectively, so that the left flange, upper cover 121, right flange and lower cover can be connected end to end to form a rectangular frame structure.

[0128] [Display component 130]

[0129] Figure 10 This is a schematic diagram of the structure of the display component in the refrigerator provided in an embodiment of this application. Figure 11 This is an exploded view of the display component in a refrigerator provided in an embodiment of this application. Figure 12 An exploded view of a display component in a refrigerator provided in an embodiment of this application.

[0130] like Figures 2 to 12As shown, in some embodiments, the refrigerator 100 may further include a display component 130 for displaying information. The display component 130 may include a display box 131, which may be detachably installed to the door 120 or embedded in the door 120. The display box 131 has a first receiving cavity 1311 for receiving a display panel 132, which is a display circuit board.

[0131] In some embodiments, an installation port is provided on the door body 120;

[0132] Display box 131 includes:

[0133] Display box 1312 is installed inside door 120 through mounting port, and display box 1312 has an opening;

[0134] Display cover 1313 is provided on the opening and located outside the door 120. Display cover 1313 and display box 1312 form a first receiving cavity 1311.

[0135] The above technical solution has the following advantages or beneficial effects: By opening an installation port on the door 120, the display box 131 can be easily installed and disassembled, simplifying the production and maintenance process. The display cover 1313 is located on the outside of the door 120, forming a first receiving cavity 1311 together with the display box 1312. The display box 1312 is embedded into the inside of the door 120 through the installation port, making reasonable use of the internal space of the refrigerator 100 door 120, without affecting the internal storage space of the refrigerator 100, providing a clean and modern appearance design, and enhancing the aesthetics of the product.

[0136] In addition, it should be noted that the first receiving cavity 1311 provides a closed environment for the display component 130, protecting it from dust, moisture and other environmental factors, and extending the service life of the component.

[0137] The design of the display cover 1313 provides an intuitive user interface, making it easier for users to operate and view information, thus improving the intelligence and user interaction experience of the refrigerator 100.

[0138] In some embodiments, the display cover 1313 is also provided with a protective member 13133, which extends toward the display box 1312. Since the sheet metal door 120 is grounded, the protective member 13133 can release static electricity in time.

[0139] like Figure 11 and Figure 12As shown, in some embodiments, the display housing 1312 is provided with a snap-fit ​​member 13121, and the display cover 1313 is provided with a snap-fit ​​groove 13131. The snap-fit ​​member 13121 extends into the snap-fit ​​groove 13131 so that the display housing 1312 and the display cover 1313 are snapped together.

[0140] The above technical solution has the following advantages or beneficial effects: the snap-fit ​​design allows the display housing 1312 and the display cover 1313 to be quickly and securely connected together without the need for additional tools or complex installation steps, simplifying the assembly process and improving production efficiency. Furthermore, the snap-fit ​​connection reduces the need for screws or other fasteners, lowering material costs and assembly time, thereby reducing overall production costs.

[0141] Furthermore, the tight fit between the snap-fit ​​connector 13121 and the snap-fit ​​slot 13131 provides a secure connection, enhancing the overall structural stability of the display box 131 and reducing the risk of loosening or detachment due to vibration or external force. The snap-fit ​​design typically achieves a seamless connection, maintaining the consistency and neatness of the display box 131's appearance and improving the product's aesthetics.

[0142] In some embodiments, there are multiple snap-fit ​​pieces 13121, which are respectively disposed at intervals on the inner walls of the left and right sides of the display housing 1312 and extend into the first receiving cavity 1311.

[0143] Correspondingly, there are multiple slots 13131, which are also spaced apart on the left and right sides of the display cover 1313 to facilitate engagement with the slot 13121.

[0144] In some embodiments, the display cover 1313 is provided with a frame that extends toward the display box 1312. The frame has a hollow structure and forms a snap-fit ​​groove 13131.

[0145] In some embodiments, at least one sound-receiving hole 13132 is provided on the display cover 1313, and the sound-receiving hole 13132 penetrates through the outer wall and the inner wall of the display cover 1313.

[0146] It should be noted that the arrangement of the microphone hole 13132 ensures that sound can be effectively transmitted to the internal microphone 141 (such as a microphone), thereby improving the reception quality and recognition accuracy of voice commands.

[0147] Specifically, the sound hole 13132 is directly opened on the display cover 1313, which simplifies the structural design of the device, reduces the need for additional components, and lowers the complexity of design and manufacturing.

[0148] In some embodiments, the display cover 1313 has a display surface located on the side opposite to the display housing 1312.

[0149] It should be noted that the outward-facing design allows users to directly see and operate the display screen, providing an intuitive and easy-to-access user interface and enhancing the user experience.

[0150] The position of the display surface allows information to be presented directly to the user, ensuring readability and visibility, and enabling clear display even under different lighting conditions.

[0151] In some embodiments, the display housing 1312 has a wiring hole 13122, which is located at the top of the display housing 131 and on one side near the upper cover 121.

[0152] It should be noted that the cable routing hole 13122 is located close to the upper cover 121, which allows the cable to be neatly introduced or led out from the top of the device and electrically connected to the sound-generating element 142 located at the upper cover 121. Due to the proximity, the cable path can be optimized, signal transmission interference and loss can be reduced, and the performance and reliability of the device can be improved.

[0153] [Voice Interaction Component 140]

[0154] Figure 13 This is a partial structural diagram of the display box inside a refrigerator from a first-view perspective, provided in an embodiment of this application. Figure 14 This is a partial structural diagram of the display box inside a refrigerator from a second perspective, provided in an embodiment of this application. Figure 15 This is a partial cross-sectional view of the display box inside a refrigerator, provided in an embodiment of this application.

[0155] like Figures 1 to 15 As shown, it should be noted that the refrigerator 100 provided in this application embodiment also includes a voice interaction component 140, which mainly enhances user experience and convenience. It can include: through voice commands, users can easily adjust the temperature settings, switch modes, or control other functions of the refrigerator 100 without manual operation. Users can use voice to inquire about the status information of the refrigerator 100, such as the current temperature, food expiration date reminders, and inventory status. For users with limited mobility or vision, voice interaction provides an accessible way to use the refrigerator. As part of a smart home system, the refrigerator 100 can interact with other devices through voice, achieving more comprehensive home automation.

[0156] like Figures 13 to 15As shown, in some embodiments, the voice interaction component 140 includes a microphone 141. The basic function of the microphone 141 is to capture the user's voice input and convert sound waves into electrical signals. This is the first step in voice interaction, ensuring that the user's commands can be received by the device. The microphone 141 is installed in a first receiving cavity 1311, i.e., located at the display panel 132. By being housed in the first receiving cavity 1311, the microphone 141 can be moved to a position closer to the display panel 132, which can reduce signal attenuation, eliminate the need for shielding wires, shorten connection cables, and reduce costs.

[0157] It should be noted that the radio component 141 is detachably installed in the first receiving cavity 1311. The detachable radio component 141 facilitates regular maintenance by the user and ensures the long-term use of the radio component 141.

[0158] In some embodiments, the detachable method may be, for example, snap-on installation, bolt installation, etc., without further limitation.

[0159] like Figure 9 As shown, the microphone 141 is located in the bottom region of the first receiving cavity 1311.

[0160] In some embodiments, the receiver 141 is a microphone.

[0161] The above technical solution has the following advantages or beneficial effects: the microphone, as a sound receiving element 141, can efficiently capture the user's voice commands, ensure the clarity and accuracy of the voice signal, thereby improving the performance of the voice recognition system.

[0162] like Figure 5 As shown, in some embodiments, the voice interaction component 140 includes a sound generator 142. The basic function of the sound generator 142 is to convert electrical signals into sound waves so that the user can hear the audio feedback from the device. This includes voice responses, prompts, alarms, etc. Through speech synthesis technology, information can be conveyed to the user in natural language, such as answering user questions, providing usage guidance, and broadcasting notifications. The sound generator 142 is mounted on the upper cover 121 and can be hidden within the upper cover 121, so that the sound generator 142 is not exposed on the exterior of the refrigerator 100, thereby improving the overall aesthetics of the refrigerator 100.

[0163] It should be noted that the sound-generating component 142 is detachably installed inside the upper cover 121. The detachable sound-generating component 142 facilitates regular maintenance by the user and ensures the long-term use of the sound-generating component 142. In some embodiments, the detachable method can be, for example, snap-on installation, bolt installation, etc., which are not limited here.

[0164] In some embodiments, the sound-emitting element 142 is a loudspeaker.

[0165] The speaker, as a sound-generating component 142, can provide high-quality audio output, ensuring that the sound feedback from the system is clear and loud, thus enhancing the user's auditory experience.

[0166] It should be noted that the combination of a microphone and speaker enables two-way voice interaction, allowing users to operate and receive feedback via voice, thus enhancing the naturalness and convenience of the interaction. The use of microphones and speakers can adapt to various voice interaction application scenarios, offering high flexibility and compatibility, and can be integrated into different products.

[0167] In some embodiments, the display component 130 and the voice interaction component 140 are located on the same door 120, which can avoid excessively long wiring harnesses and improve the interactive effect.

[0168] like Figure 9 As shown, in some embodiments, the voice interaction component 140 includes a main control board 143, which is responsible for receiving audio signals from the receiver 141 (microphone) and performing preliminary signal processing, such as noise reduction and gain adjustment, to improve the accuracy of voice recognition.

[0169] The main control board 143 can process and store data related to voice interaction, such as user command history and system logs, for analysis and optimization. The main control board 143 typically has the ability to communicate with other devices or networks, and can exchange data with smart home systems, cloud services, or mobile applications via wireless or wired connections.

[0170] Based on the results of voice recognition, the main control board 143 is responsible for executing corresponding instructions, such as adjusting the temperature of the refrigerator 100, setting reminders, or playing audio feedback. Specifically, reminder feedback can be generated through a transmitter. In addition, visual or graphic feedback can also be displayed through the display screen or display surface of the display component 130.

[0171] In contrast to the existing solution where the display board 132 and the main control board 143 are installed separately and require their own power supplies, the display board 132 and the main control board 143 in this application are stacked together, and the two circuit boards can share a single power supply, which reduces connection complexity and lowers costs.

[0172] like Figure 9 As shown, in some embodiments, the display panel 132 has a mounting area 1321, and the main control board 143 is integrated in the mounting area 1321.

[0173] The above technical solution has the following advantages or beneficial effects: By directly mounting the main control board 143 in the mounting area 1321 of the display board 132, the internal space occupied by the device is reduced, making the device design more compact and integrated. The integrated design reduces the number of components that need to be manufactured and assembled separately, thereby reducing manufacturing and assembly costs. The direct connection between the main control board 143 and the display board 132 shortens the signal transmission path, reducing signal delay and attenuation.

[0174] In addition, the integrated design simplifies the internal structure of the equipment, making troubleshooting and repair easier and faster, and reducing maintenance costs.

[0175] In some embodiments, the mounting area 1321 is located on the side wall of the display panel 132, wherein, in the first direction X, the projection surface of the main control board 143 is located on the mounting area 1321 of the display panel 132, that is, along the first direction X, the size of the main control board 143 is smaller than the size of the display panel 132.

[0176] like Figure 9 As shown, in some embodiments, an inner door liner is provided on the inner side wall of the door body 120;

[0177] The refrigerator 100 also includes a protective member 150, which is disposed on the outer wall of the display box 131 and located between the display box 131 and the inner liner of the door. Along the first direction, the projection of the protective member 150 is located on the mounting area 1321.

[0178] The above technical solution has the following advantages or beneficial effects: After the main control board 143 is integrated with the display board 132, the thickness of the display box 131 at the installation area 1321 is increased, the distance between the display box 131 and the inner liner of the door is reduced, and there is a risk of condensation. The protective component 150 can play a role in preventing condensation.

[0179] In addition, the protective component 150 prevents condensation and protects key electronic components such as the main control board 143 and the display board 132, extending their service life.

[0180] In some embodiments, the protective element 150 is aluminum foil, which is thin and does not significantly increase the weight or thickness of the device.

[0181] like Figure 13 and Figure 14 As shown, in some embodiments, the refrigerator 100 further includes an isolation member 160, which is disposed on the display box 131 and surrounds at least a portion of the periphery of the radio member 141.

[0182] The above technical solution has the following advantages or beneficial effects: the isolator 160 can effectively isolate the radio receiver 141 from electrostatic interference from the external environment, reduce the risk of electrostatic accumulation, and prevent electrostatic breakdown from damaging the radio receiver 141 and related electronic components. By preventing electrostatic breakdown, the isolator 160 protects the normal function of the radio receiver 141, reduces equipment downtime or performance degradation caused by electrostatic faults, and improves the overall reliability of the refrigerator 100.

[0183] The analysis is as follows: The microphone 141 is located near the edge of the notch in the door 120 and on the bottom side of the display box 131. In other words, it is installed close to the edge of the door 120, which poses a risk of electrostatic discharge. Electrostatic discharge may cause permanent damage to the electronic components. The microphone 141 is separated from the edge of the notch in the door 120 by the isolator 160 to prevent electrostatic discharge. The use of the isolator 160 reduces this risk, thereby extending the service life of the microphone 141 and other related electronic components.

[0184] In some embodiments, the spacer 160 may be made of plastic.

[0185] In some embodiments, the isolator 160 can be adjusted to suit different device layouts and component configurations based on specific design requirements without significantly increasing design complexity or cost.

[0186] like Figure 15 As shown, in some embodiments, the refrigerator 100 further includes an abutment 170 disposed on the display housing 1312 and extending toward the radio 141, such that the radio 141 abuts between the abutment 170 and the display cover 1313.

[0187] The above technical solution has the following advantages or beneficial effects: the addition of the abutment 170, which presses against the microphone 141, makes the microphone 141 fit tightly against the inner wall of the display cover 1313, thereby reducing sound loss when sound is transmitted from the outside to the inside. At the same time, it can further improve the installation stability of the microphone 141.

[0188] In some embodiments, the first end of the abutment 170 is fixedly connected to the inner wall of the display housing 1312, and the second end of the abutment 170 extends along the direction facing the display cover 1313 until it presses against the microphone 141 disposed on the display cover 1313. This reduces sound loss and improves the installation stability of the microphone 141.

[0189] like Figure 13 and Figure 14 As shown, in some embodiments, the display cover 1313 is also provided with a plurality of hooks 13134, and the microphone 141 may be provided with corresponding hook grooves. The hooks 13134 and the hook grooves match to install the microphone 141 on the display cover 1313.

[0190] For example, the microphone 141 can be first attached to the inner wall of the display cover 1313 with adhesive backing. Then, it is secured to the display cover 1313 by the setting of the hook 13134 and the hook groove. Furthermore, in order to further improve the installation strength of the microphone 141, the abutment member 170 is used to press it to make the installation more stable. Since the abutment member 170 always provides a certain squeezing force to the microphone 141, the microphone 141 can be completely and tightly attached to the inner wall of the display cover 1313.

[0191] In some embodiments, foam protection is added between the microphone 141 and the second end of the abutment 170 to prevent the microphone 141 from being crushed.

[0192] In some embodiments, the abutment 170 is an abutment plate, and the abutment 170 has an abutment portion that abuts against the side of the microphone 141 to fix the microphone 141 to the inner wall of the display cover 1313.

[0193] It should be noted that the abutting portion extends towards the microphone 141 and presses it against the inner wall of the display cover 1313. This design ensures the stable fixation of the microphone 141 within the first receiving cavity 1311, preventing displacement or loosening during use.

[0194] Furthermore, this design simplifies the installation process. The natural extension of the contact portion and its contact with the inner wall allow for quick and easy securing and positioning of components, reducing installation time and complexity. By ensuring the stability and safety of the radio 141 and other components, the overall product reliability and lifespan are improved, reducing the risk of malfunctions due to component loosening or displacement.

[0195] In some embodiments, the radio 141 is provided with an indicator light.

[0196] It should be noted that since the microphone 141 sometimes fails to respond after receiving the user's voice signal, an indicator light can be added. When the microphone 141 receives a signal, the indicator light will light up accordingly to remind the user.

[0197] In some embodiments, the upper cover 121 has a second receiving cavity 1211, the opening of the second receiving cavity 1211 facing the lower side of the door body 120, and the sound-emitting element 142 is installed in the second receiving cavity 1211.

[0198] In some embodiments, the sound-emitting element 142 is installed in the second receiving cavity 1211, that is, located at the upper end cover 121. By being housed in the second receiving cavity 1211, the sound-emitting element 142 can be hidden in the upper end cover 121 and is not exposed on the exterior of the refrigerator 100, thereby improving the overall aesthetics of the refrigerator 100.

[0199] It should be noted that the sound-generating component 142 is detachably installed within the second receiving cavity 1211. The detachable sound-generating component 142 facilitates regular maintenance by the user and ensures its long-term use. In some embodiments, the detachable method may be, for example, snap-fit ​​installation or bolt installation, etc., which are not further limited here.

[0200] In some embodiments, the door 120 further includes an upper cover plate 122, which covers the upper cover 121.

[0201] The above technical solution has the following advantages or beneficial effects: by covering the upper end cover 121 with the upper cover plate 122, the sound-generating component 142 can be effectively protected from external environmental influences, such as dust, moisture and physical damage, thereby improving its durability and reliability.

[0202] In some embodiments, the upper cover 122 has a plurality of sound holes 1221.

[0203] It should be noted that the design of multiple sound holes 1221 allows for more even sound propagation, resulting in clearer and louder audio output and enhancing the user's listening experience. Furthermore, the strategic arrangement of the sound holes 1221 reduces sound reflection and interference during propagation, lowering distortion and improving sound quality.

[0204] In some embodiments, a sound-emitting mark may also be provided at the sound-emitting hole 1221 to remind the user of the sound-emitting location. The sound-emitting hole 1221 may be a plurality of small holes with a certain aperture evenly arranged. The corresponding arrangement of the sound-emitting element 142 and the sound-emitting hole 1221 can effectively improve the effect of outputting voice information.

[0205] In some embodiments, the upper cover 121 is provided with a fixing post 1212, and the voice interaction component 140 further includes a fastener, and the upper cover 122 is fixed to the fixing post 1212 by the fastener.

[0206] The combination of fixing posts 1212 and fasteners ensures a secure connection between the upper cover plate 122 and the upper end cover 121, preventing loosening or displacement due to vibration or external forces during use. The fixing posts 1212 provide clear positioning points, making the installation process of the upper cover plate 122 simpler and more efficient, reducing alignment and adjustment time.

[0207] In some embodiments, there are multiple fixing posts 1212 and fasteners to improve the installation strength of the upper cover plate 122.

[0208] The refrigerator provided in this application embodiment includes: a cabinet having a refrigeration compartment; a door movably connected to the cabinet and configured to open and close the refrigeration compartment, the door including: an upper cover located at the top of the door; a display assembly including: a display box installed on the upper part of the door, the display box having a first receiving cavity; a display panel installed in the first receiving cavity; a voice interaction assembly including: a microphone installed in the first receiving cavity; a sound emitter electrically connected to the microphone and installed on the bottom surface of the upper cover; and a main control board disposed on the display panel, and the main control board electrically connected to the display panel, the microphone, and the sound emitter respectively; wherein, the display panel and the main control board are stacked along a first direction, the first direction being the direction from the front side of the cabinet to the rear side of the cabinet.

[0209] By incorporating a voice interaction component, with the receiver and speaker located on the same upper and lower cover of the same door, the refrigerator achieves voice interaction functionality and enhances intelligent services. This avoids the need for complex electronic devices like smart displays, reducing potential points of failure and minimizing hardware costs and complexity, thus effectively lowering production costs and facilitating repairs in case of malfunction. Furthermore, the receiver and speaker are concealed within the door, not exposed on the outside, resulting in a cleaner and more modern appearance, enhancing the overall aesthetics and preventing external interference with the design, ultimately improving the user experience.

[0210] In addition, such as Figures 1 to 15 As shown, this application embodiment also provides a refrigerator 100, including: a cabinet 110 having a refrigeration compartment; a door 120 movably connected to the cabinet 110 and configured to open and close the refrigeration compartment, the door 120 including: a display panel 132 installed on the door 120; a voice interaction component 140 including: a microphone 141 disposed on the display panel 132 for receiving voice information; a speaker 142 electrically connected to the microphone 141 and installed on the top of the door 120; a main control board 143 disposed on the side of the display panel 132 and facing the refrigeration compartment; when the microphone 141 receives voice information, the main control board 143 controls the speaker 142 to provide sound feedback, and the main control board 143 controls the display panel 132 to provide display feedback.

[0211] The refrigerator provided in this application embodiment, through the setting of a voice interaction component and a display component, with the display component installed on the door at the same height as a person, and the microphone installed inside the display box at the same height as a person, is conducive to better reception of voice commands, resulting in less loss of voice signal during transmission and thus improving the accuracy of voice recognition. In addition, the closer distance between the microphone and the display board shortens the length of the connecting cable, which not only reduces material costs but also reduces the risk of signal attenuation and may eliminate the need for additional shielding of the signal cable. Furthermore, the integration of the main control board and the display board allows them to share a power supply, reducing connection complexity and further reducing production and maintenance costs, while making more efficient use of the internal space of the display box.
